Download Files From Internet & Read File?
Mar 3, 2008
I need to download files from internet without using FTP, here's my idea:To check version of the program and also download updates.So firstly, when the user enters the splash screen there is a timer which will check updates (downloadTimer) so then downloadTimer starts to download this txt file http://localhost/version.txt and then when its downloaded (and replaced the old one that was on the computer already) and then after that, read the file. If the version.txt contains version 1.0 then pass the check and splash screen closes, main form opens, else then msgbox ("Please Wait!" & vbcrlf & "Downloading updates") and then download updates with the same way from downloading version.txtOh! and also when the file is downloaded (version.txt) save it to "c:programMyApplicationversion" downloading the file without using FTP (if there isn't any other way i could use FTP).File reading could be made with an IO.FileStream thingy.So how do i do the download part?

Okay, I will be passed in an internet address that resolves to a file of some type (.xml, .zip, .mp3, whatever). From inside my VB .NET 2005 program, I need to transfer the file down to the local machine... preferably with events so I can update the screen to show download progress. I also need a way to detect if the file specified by the user actually exists, and retrieve it's file size and compute an estimated download time.

I have looked at many other examples that show how download a file from the internet however, these examples don't work because the website I want to download these files from is secure so I don't know how to do this. I am using visual basic express 2008.

I'm trying to create a simple file downloader (with GUI). I'm pretty new to Vb.net and I didn't find any usefull information about this in the books I own. All tutorials in the wild are making me more frustrated, since the snippets I use, in most cases, are different classes.What should I use? HttpWebRequest/HttpWebResponse or FileWebRequest/FileWebResponse?How do I save the ResponseStream to a file ?Is it possible to use ResponseStream to define the kind of File (FileInfo) Class to get basic file information (size, extension, etc) is it generally neccessary, if GetResponse().headers gives you most of this info ?
My code, which sucks, because I do not know how to realize the saving....
Private Sub btn_downloader_Click(ByVal sender...) Handles btn_downloader.Click
'e.g http://codeigniter.com/download.php'
Dim fileUrl As String = txtBox_url.Text
Dim webUri = New Uri(fileUrl)
[code]....
but I don't know what the buffer is and what it is for. Should I set some static values or any dynamic which deppends on Stream-data ?

I wrote a program to download and play AVI files the files are large in size and long time wise. I have the files playing as they are being downloaded but i can't see how long the file is or seek reliably. i was reading that the AVI headers are in the last 512kb of the AVI file *why would't they put it at the start* lol so my question is is there a way to download the last 512Kb of the file i'm downloading. i have the Bytes Read and Length of the file while its downlaoding i'm just not sure where to go from there, or how to do it atleast. If i had the length in time of the Avi file i could set the trackbar to be able to seek properly. or if someone has an idea how i could get the time of the video by using fps and some math i could prob do it that way too but idk how i would tell how i can find how many kb are in the fps i'm sure it changes so think that way is't going to be reliable. how to get the last 512kb would be the best option not sure if it can be done even.

Reading a .txt file in VB.net. My file path is C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt.
This is my line of Dim LoanOptionsFile As String = "C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt"
I can read the file when I run the program, but how do I write the file path so that someone else can download my program and file and read the file on their system?

and get the internet address associated with it.

I have a database table where the user marks files to be downloaded. Subsequently, I browse this table and need to create a fileList to pass to an ActiveX downloader. My routine works locally and on the server for ONLY the first file. I know my logic must be bad, but I cannot find it. All of these files are always in the same server directory which is as follows:
"D:inetpubvhostsWebSite.comsessionVideos"
Sub (GetFileList)
Dim dtVideosSelected As New DataTable

I'm working on a website in which a user enters a name and then presses a button that prompts the server to create a pdf file according to the information provided, and then sends the file to the user.
I'm testing the website on my laptop without IIS.I needed the pdf to be hebrew and couldn't find a pdfwrite with vb on hebrew; instead, I create a MS Word document and then convert it to pdf using the code below.
This works fine on Firefox, Chrome, and Safari, but on Internet Explorer the page disconnects before the download. It disconnects when the create word statement is executed.

i have a program that calculate a download and up load speed for internet , and i'm doing this by the following for download
1. but the whole code in a timer with interval 1 second
2. calculate the total byte recieved and store it in a variable (s)
3. calculate the new value of total byte received and store it in (s1)
4. s2=s1-s
5. s2 represent the difference in an interval within 1 second is that a download speed ?
i test it with downloading some files from internet using mozilla firefox the values is so close to each other but is that the right way to measure the speed ???

When I click programmatically on a Download link in a webpage, IE 9 does not allow me to automatically download, I have to click on Open, Save or Cancel.
How can I make the selection (Open, Save or Cancel) programmatically?
At the moment I am using the sendkeys command, but, as we know, it is not reliable.
I also do not want to program a mouse click because it is cumbersome and because even in full screen one has to factor in the zoom factor.
I am using SHDocVw.InternetExplorer
The Webbrowser will also do.
